' Application April 20, 1942, Serial No. 439,623

Claims. lCl. 292-265) My invention relates to an improvement in window fasteners, wherein it is desired to provide a simple and efiicient type of fastener for supporting a pivoted window in adjusted relation with respect to its frame.

The object of the present invention is to avoid previously encountered difficulties in the formation of fasteners of this general type. With my construction, I desire to avoid the necessity of locking the bracket arms when the window is closed. I also desire to provide a construction which will not rattle when the window is open to an adjusted position.

An object of the present invention lies in the provision of bracket arms which are angularlyshaped in cross-section. This construction stifiens the arms and prevents injury to the arms due to the bending of the arms in use. This construction also serves to maintain the arms in proper relation to the brackets, as with this construction the arms can not readily be bent out of shape. 7

It is a further object of my invention to provide a bracket over which the bracket arm may pivot and which is so arranged with respect to the pivot connecting the bracket arm to the window that an outward pull on the window will not tend to pivot the bracket arm. With this arrangement the bracket arms may be pivoted into vertical position without danger of having an outward force upon the window swing the arms into horizontal position so that the window may open. Thus, when the bracket arms are folded down into. substantially parallel relation with the closed window, the window is locked from outward movement.

A further feature of the present invention lies in the provision of a wedge-shaped receiving element on the bracket for receiving the bracket arm. When the bracket arm is engaged in this wedge-shaped notch, the arm is firmly held by the bracket and the bracket arm can not rattle with respect to the bracket.

These and other objects and novel features of my invention will be more clearly and fully set forth in the following specification and claims.

In the drawing forming a part of my specification:

Figure 1 is a perspective view of my window fastener in operation.

Figure 2 is a side elevation view of the window fastener in closed position thereof.

Figure 3 is an elevation View of the bracket or stile plate secured to the window frame, showing in cross-section the relation of the bracket arm engaged thereto.

Figure 4 is a view similar to Figure 3 showing the position of the bracket arm with respect to the bracket when the window is being opened or closed.

Figure 5 is a side elevation view of the bracket or stile plate showing the relation of the bracket arm with respect thereto.

The storm window fastener A includes a bracket I arm B, which is pivotally secured to the window C. As will be clearly understood the fastener A is adaptable for various purposes, but is usually used for holding a storm Window or the like in adjusted relation with respect to the window frame.

The bracket arm, indicated in general by the letter B, comprises an elongated arm I0, which is preferably right angular in cross-sectional shape, and which includes a substantially vertical flange II which extends on a substantially vertical plane, and a right angularly extending flange it. In the form illustrated, the flange ll terminates at the extreme free end of the arm Ill, and the flange l2 continues to form a turneddown handle end l3, by means of which the position of the bracket arm may be regulated.

An attaching plate I4 is provided on the storm window C, which is secured to the storm window by means of attaching screws 15, or the like. The attaching plate or bracket i4 is right angular in cross-section and it includes a flange 16 designed to overlie the surface of the window C and through which the screws [5 extend, and a second flange I'I extending substantially normal to the surface of the window C. The right angular arm 13 is pivotally attached to the attaching bracket 14 by means of a pivot l9 which extends through the flange I1 and through the vertical flange H of the angular arm Ill.

The stile plate or bracket plate D comprises a base 26 designed to lie flush against the surface of the window frame E, and attaching bolts 21, or other suitable fastening means extend through the plate 2!] to attach this bracket plate to the window frame. A flange 22 extends outwardly from the plate 20 at substantially right angles with respect thereto, and this plate 22 is preferably arranged angularly with respect to the vertical edges of the base 20. In other words, the flange 22 is preferably arranged so that when the window bracket arm B is holding the window in open position, the arm will extend at substantially right angles with respect to the flange 22.

The flange 22 includes a substantially V-shaped or wedge-shaped slot 23 which is designed to receive the bracket arm B. The upper extremity 24 of the flange 22 is positioned substantially in horizontal alignment with the pivot 19 in closed position of the window, as best illustrated in Figure 2 of the drawing. As a result the window may be locked in closed position, as will be later described in detail.

The angularly extending flange l2 of the angular arm I0 is provided with a series of spaced ceive the flange 22, as best illustrated in Figure 1 of the drawing. The upper end of the flange 22 is slightly wider than the portion of this flange adjacent the slot 23 in order to hold the bracket arm in sli'dable relation with the bracket, as will be later described.

In operation, the angular arm in normally rests upon the upper extremity 24 of the flange 22, as illustrated in dotted outline in Figure of the drawing, and as illustrated in full outline in Figure 4 of the drawing. As will be noted from an examination of Figure 4 of the drawing, the notches 25 do not extend the full width of the flange I2, so that the bracket arm may be slid along the upper extremity 24 of the bracket flange 22. In other words, as the window C is swung into open or closed position, the bracket arm [0 does not have a tendency to engage the flange 22 of the stile or bracket plate 20, as the flange it" of the bracket arm will be supported upon the upper extremity 24. When it is desired to. support the window in open position, the window is swung to the desired open position and the free end l3 of this arm is then drawn inwardly toward the center of the window frame a short distance. The flange 22 will then engage ina notch 25, as illustrated in dotted outline in Figure 4 of the drawing, and the bracket arm may be swung downwardly into the receiving notch 23.

When the bracket arm i0 is moved into the position illustrated in dotted outline in Figure 4 of the drawing, the transverse pressure on the end of the arm may be released and the downward pivoting of the arm may continue. As the arm l0 pivots downwardly, the notch 25, embracing the flange 22, remains in engagement with the flange.

Downward movement of the bracket arm from the position illustrated in dotted outline in Figure 4 allows the arm to swing outwardly into its normal relation, this downward movement being continued until the vertical flange H engages the outer surface 25 of the notch 23. The V-shape or wedge-shape of the notch 23 causes the arm to be wedged into locked position, this wedging action acting to clamp the bracket arm in the notch and to thereby prevent any relative movement between the bracket arm and the bracket or stile plate.

When it is desired to pivot the window to a further open position, or to a closed position the end l3 of the bracket arm is raised. This raising of the bracket arm causes the arm to be sprung inwardly, the arm passing from the position 11- lustrated in Figure 3 through the position illustrated in dotted outline in Figure 4, to the position illustrated in full lines in this figure. The flange I2 is then resting upon the upper extremity 24, of the flange 22 of the bracket or stile plate D, allowing pivotal movement of the window C.

In closing the window C, the window'is pulled inwardly by the bracket arm until the attaching bracket 14 comes into overlapping relation with the stile or bracket plate D. The position of the bracket plate D is so related to the closed position of the attaching plate N that the pivot It will be just outwardly of the upper extremity 24 of the flange 22. As a result the downward move-' the outward movementis blocked by the flange 22. Furthermore, as the upper edge of the flange 22 is substantially opposite to the pivot I9, there is little or no tendency for the bracket arm to pivot when such an outward force on the window is exerted. As a result no separate locking means is required and it is not necessary that the bracket arm be held by some additional means in substantially vertical position in parallel relation to the window C in order that the window be locked in closed position.

In accordance with the patent statutes, I have described the principles of construction and operation of my window fastener, and while I have endeavored to set forth the best embodiment thereof, I desire to have it understood that obvious changes may be made within the scope of the following claims, without departing from the spirit of my invention.
